Randomized Controlled Trial Clinical TrialThe efficacy of adding a continuous intravenous morphine infusion to patient-controlled analgesia (PCA) in abdominal surgery.
The effect of adding a continuous infusion of morphine 1 mg/hr to patient-controlled intravenous analgesia was studied in a randomized double-blind trial. Ninety-six patients scheduled for abdominal surgery were enrolled; 38 received PCA and continuous infusion (PCA + C), 45 received PCA alone and 13 were excluded because of protocol violations. PCA was delivered via an ABBOTT 4200 pump with settings of morphine 1 mg bolus and five-minute lockout in both groups. ⋯ The PCA group delivered more PCA morphine during 0500-0800 hours and 0800-2200 hours on the first day only. There was no significant difference in the D/D ratio for any time period during the three days. Total morphine delivery was greater in the PCA + C group on the second and third postoperative days (P = 0.009 and P = 0.0001 respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical TrialA double-blind randomized prospective study comparing ondansetron with droperidol in the prevention of emesis following strabismus surgery.
A prospective double-blind study was conducted to compare the anti-emetic efficacy of ondansetron and droperidol in preventing postoperative emesis following strabismus surgery. A sample size of 213 patients was divided into three equal groups to receive ondansetron 150 micrograms/kg (Group A), ondansetron 75 micrograms/kg (Group B), or droperidol 75 micrograms/kg (Group C). All patients received a standardized anaesthetic technique. ⋯ Mean time to discharge from the recovery room was 75.3 minutes (Group A), 44.4 minutes (Group B), and 41.0 minutes (Group C). The mean time to tolerating oral fluids was 356.5 minutes (Group A), 402.8 minutes (Group B), and 378.1 minutes (Group C). There was no statistical difference in discharge times from recovery or time to tolerating oral fluids in any of the three groups.
